18 Claims. (Cl. 93-1) 'Ihis invention relates to an apparatus for making or forming wrappers in which articles may be wrapped.

An object of the invention is to provide a new and improved apparatus or feeding and cutting mechanism for feeding a strip of tape to a predetermined position with respect to a web of paper or wrapping material which is being fed, and applying the tape, which has been cut, to the material at such an angle as to cause the end of the tape to overlie the edge of the material a predetermined distance, whereby a iin--V ished wrapper with an opening tape, of the type disclosed in Patent No. 2,019,191 issued to Michael J. Milmoe is produced.

A further object of the invention is to provide a mechanism for feeding and cutting a strip of tape, for feeding a web of Wrapping material and feeding the tape in proper timed relation with the material being fed, to properly bring the tapeA and the material to a predetermined position at a predetermined time. 4

'A further object of the invention is to provide a mechanism which feeds and cuts a strip of tape, superposing the cut tape upon a sheet of wrapping material which has had a narrow portion of wax applied thereto for adhering the tape to the material to provide a laminated sheet or wrapper. I

An additional object of the invention is to provide a method for producing a laminated material which consists of cutting a strip of tape and feeding it into a position for superposing it on a sheet of pre-waxed wrapping material for the purpose of adhering the tape thereto.

A` further object of the invention is to provide a mechanism which includes means for cutting and then feeding a strip of tape to a predetermined position with respect to a sheet of paper being fed, which is provided with means for adhering the cut tape in superposed relation on the wrapping material and arranging the tape at such an angle to cause the end of the tape to overlie the edge of the paper to provide a tearing strip, and the provision of means for cutting the material at a point adjacent the end of the overlying strip of tape.

Numerous other objects and advantages will be apparent throughout the progress of the following specification.

Referring to the drawings, and more particularly to Figs. 1 and 2 thereof, I designates a suitable frame or supporting structure which has journaled at an upper portion thereof, in any conventional manner, a. transverse shaft 2, upon which is mounted a guide roller 3. Paper, or other desirable Wrapping material 4, is fed from a supply roll to and aboutv the guide roller 3 into contact with a waxing roller 5. 'Ihe wax roller 5 is xed to a shaft 6, Fig. 5, which shaft 6 is journaled in bearings 'l and 8 of a frame 9 supporting the wax pot or bath I0. 'I'he frame 9, containing the wax pot III, is attached to the main frame or support I of the apparatus by the bracket members I I and I2', Figs. 1 and 5.

4At the bottom of the frame 9 there are recess bearings I3 and I4, Fig. 1, which contain heating units I5 for heating the wax in the pot I0 to the proper temperature to keep the Ywax in melted condition.

The shaft 6, upon which is mounted the wax roll`5, is immediately adjacent a shaft I6, Figs. 1 and 5, which latter shaft is adjustable with respect to the shaft 6. The shaft I6 is provided with a recessed portion I1 and is adapted to cooperate with the enlarged or platen portion I8 on the roll 5. The shaft I6 is adapted to be shifted in its bearings I9 so as to bring an edge I1a either closer or farther away from the platen portion I8 to increase or decrease the space between the platen portion whereby the amountV of wax on the platen portion I8 can be determined. The space between the recess I1 and the high spot I8 therefore controls the thickness of the Wax and this thickness is determined by the adjustability of the shaft I6.

A bracket arm 2l is xed to the end of the shaft I6 and extends forwardly, as clearly indicated in Figs. 1 and 5. This bracket arm 2I has an opening in its outer end to the right, Fig. 1, through which a screw 22 extends. 'I'his screw 22 threadedly engages a block or boss 22a, Fig. 1, on a part of the main frame or supporting structure. A wing nut 23 threadedly engages the upper end of the screw 22 and determines the amount of adjustment given to the shaft I6, there being a spring 24 arranged between the under side of the bracket 2| and the upper side of the boss 22a. Therefore, by operating the wing nut 23,`the bracket 2I will be moved and consequently turn the shaft I6 in its bearing I9 to bring an edge I1a of the recess closer or farther away from the enlarged or platen portion I 8 on the wax roll 5. Adjustment, therefore, can be made to govern whatever thickness of wax may be desired. The purpose for the regulation of the amount of wax is to prevent too much wax upon the high spot I8 of the roller 5 from being applied to the material 4 which might subsequently spread over the remainder of the material.

'Ihe material or paper 4, which is being fed about the roller 3, Fig. 1, comes in contact with the platen I8 of the roller 5, which is rotating through the wax bath I I), and deposits on the paper or other wrapper material the proper amount of wax. The wax is disposed on the material 4 an an angular position equivalent to the formation of the platen I8, and is also of a substantially equivalent width, Fig. 5.

'I'he paper 4 is further fed around tension guide rollers 25, 2B and 21, Fig. 1, which are rotatably mounted on shafts 28, 29, and 30 respectively. The shafts 28, 29 and 3U are rigidly mounted on the frame I. 'Ihe feed of the paper 4', with its waxed portions, continues from roll 21 into contact with the superposing or pressing rolls 3I and 32, Fig. 1, where it is adapted to receive a strip of tape.

A transverse stationary shaft 33, Figs. 1 and 2, which is located at the left of the apparatus, immediately to the left of the wax bath frame 9, is fixed to the main frame I. The shaft 33 has mounted thereon a rotating tape supply roll 34, from which tape 35 is fed into the apparatus. Journaled to the frame I at 36 is an arm 31, Fig. 1, which acts as a friction arm for the tape supply roll 34 for supplying tension to the roll 34 to prevent unnecessary unrolling of the tape. 'Ihe tape is fed from the roll 34 into guide members 38 which are disposed vertically in order to turn the tape over to a vertical position causing the tape to come off the spool at a proper angle at all times. To the left of the vertical guides 38 is an angularly disposed channel guide member 39, Figs. 1 and 2, which is rigidly secured to the frame I by the bracket member 48. The channel guide receives the tape coming from the vertical guides 38 and turns thetape back to its flat horizontal position as it is being fed downwardly into the channel. The guide member 39 has a heating element 4I contained therein, which heats and irons out the tape as it passes through the channel guide member 39, in order to eliminate any Wrinkles or creases which might be present.

At the lower end of the guide member 39 and immediately adjacent thereto is a horizontal guide channel 42 which is attached to the frame in any suitable manner, and receives the tape from the guide member 39, the tape moving past a. guide pin 43. This guide pin 43 assists in guiding the tape into the channel 42. At the forward end of the channel 42 are feed rolls 44 and 45 which are mounted upon parallel shafts 46 and 41, respectively, Fig. 1. The shaft 41 is journaled to the frame by the bearing 48, which is integral with the extension 49 of the frame I. The upper shaft 46 is the drive shaft, and has a drive gear 50, Fig. 2, contacting a lower gear (not shown) on the shaft 41. 'Ihese latter gears cooperate to rotate the rolls 44 and 45 to feed the tape 35.

Immediately beyond the feed rolls 44 and 45, and substantially in the same parallel plane, is a pair of cutter rolls 5I and 52, Figs. 1 and 6, which is mounted on shafts 53 and 54, respectively. The shaft 54 is journaled at one side to the frame I by the bearing 55, and the shaft 53 is journaled by the bearing 56 which is integrally connected with the arm 51 and extends from the bearing 55 in the extension 58 of the frame I, Figs. 1 and 3. The bearing 56, arm 51 and extension 58 are rigid parts of the frame I. The shaft 54 is the actu ating shaft and is connected by a universal coupling 59, Figs. 2 and 3, to the shaft 60 which is rotated by a gear 6I Fig. 2.

'Ihe upper cutter roll 5I, Fig. 6, is driven `by the lower roll 52 through conventional gear mechanism. The upper roll 5I is provided with a cutter knife 62 co-operating with a cutter knife 63 in the lower roll 52 to intermittently cut the tape ofi' in predetermined lengths to provide tearing strips. The cutter rolls 5I and 52 are constantly rotated, and cut a piece of tape on every rotation, in synchronization with vthe feed of the tape.

Lying adjacent and immediately beyond the cutter rolls 5I and 52 is a channel guide 64 attached to the frame I by means of a bracket 65 Fig. 1. l

Above the guide 64 and fixed to the frame, is a transverse extending bracket arm 61, Figs. 1 and 3. At one end of the bracket arm 61 is a vertical recess 68 which receives a vertical shaft 69. Around the shaft 69 and below the bracket arm 61 is a vertically disposed bearing 10 which has integrally connected thereto an angular pusher arm or bar 1I. 'Ihis arm is of angular configuration and extends horizontally to the side and beyond feed rolls 12 and 13.

A bearing 66 is integral with the arm 61 and carries a pivotally or swingingly mounted lever arm 14, Figs. 1 and 3. At the end of the extension arm 14 is a bearing 15, to which is journaled a rotatable shaft 16. The upper feed roll 13 is mounted on the shaft 16 While the lower feed roll 12 is mounted upon a rotatable shaft 11. The shaft 11 is journaled at one end to the bearing 18, Fig. 1, which bearing is integral with the extension 19 of the frame I. 'I'he op to co-operate with a roller 8|, Fig. 2, which is As the'shaft 16 pos'i end of the shaft 11 is journaied` to the frame I, and carries a gear (not shown) which co-operates with an upper gear 88, Fig. 3, to drive the upper shaft 16 and the Yfeed roll 13. 'I'he shaft 16 also carries a barrel cam which is rotated with the shaft 16, and this cam is adapted mounted on the pusher bar 1|. is rotated by the lower shaft 11, the cam 8| will be rotated to position the high spot of the barrel `cam into engagement with the roller 8| on the pusher bar 1|, causing the barI 1| to be pushed into see Figs. 10, 11 and 12. The lower roll 3| is.

contact with the tape 35, the tape being fed by the feed rolls 12 and,13, into and against a guide 82, Figs. 1, 2, 9 and 9A, to properlyposition the tape 35. A spring 83, Fig. 2, is attached at one end to the pusher arm and at the other end to the frame I and moves the arm back when the high spot of the cam is not contacting the roller 8|. 'I'he guide 82 is disposed beyond the feed rolls l2 and 13 and is bracketed to the frame I by the bracket 84, Fig. l. The barrel cam, in co-operating with the roller 8| of the pusher arm, can move the pusher arm 1| since this arm 1| is integral with theI vertical bearing 18, which is lrotatable on the vertical shaft 69.

The tape 35 moves forwardly to the right, Fig. 1, at an acute. angular position with respect to an edge of the web of Wrapping material 4 and at an angle with lrespect to the plane of the wrapping material. When the tape reaches the position shown at the point indicated at A, Fig. 2, the cut strip of tape will become adhesively attached to the Wrapper 4 at which time it will lie in the plane of the wrapper 4 but at an acute angle with respect to the edge of the wrapper. The guide arm 1|, which is controlled by a cam as previously mentioned, therefore guides the tape in its angular position until it is just about ready to be attached to the wrapper when the cam will cause the guide arm to swing backwards toward the top, as viewed in Fig. 2, to permit the new movement of the tape when it is attached to the Wrapper. The pusher arm 1|, therefore, pushes the tape into the guide 82 and holds the tape within the recess formed in the guide, Fig. 9A, until the tape is to be transferred to the wrapper at which time the cam will cause the pusher arm 1| to swing back slightly to permit the said transfer. However, after the transfer has been made the pusher arm 'IIA will move back again to the position shown in Fig. 9A and cause the tape 35 again to assume its angular position.

The guide 82 is provided with a cut-out portion, as indicated in Fig. 9A, into which the tape 35 is received as it is riding on the surface of the part of the frame or supporting member I.

The guide members, and the feed rolls which feed and guide the tape 35, are so disposed with respect to the feeding position of the waxed material or paper 4, that the tape 35 is fed at an angular position to the paper, Figs. 2 and 3. The synchronizing of the feed of the tape 35 with that of the feed of the paper 4 brings-a icut piece of tape into exact underlying. pos'ition with the waxed portion of the paper as 'the tape and paper are engaged by the pressing rolls 3| and 32.

The superposing or pressing rolls 3| and 32 are adjacent the end of the channel guide 82v and the pusher arm or bar 1|. The purpose of these rollers is to press a cut piece or strip of tape 35 into contact with the waxed portion of the paper 4, to cause the tape to be adhered to the paper 4,

enlarged with respect to upper roll 32 and has a transverse extension 85, Figs. 9 and 10, and a recessed or core portion 86 therein, Fig. 10. The core 86 is adapted to receivea rigid shaft 81 which has a hollow recess or portion 88, which contains aheating unit 89. The shaft 81 and the heating unit 89 are mounted in a stud bearing 98 which is integrally connected to the frameby a bracket 9|, Fig. 1. The stud bearing 90 lies adjacent the lower roll 3| and bolts the shaft 81 to the frame, Fig, 10.v The coremember, whichv contains the shaft 81 and the heating unit 89, has the further purpose of decreasing the Weight of the lower roller 3|, and at the extreme end of th-e extension 85 there is provided a smaller recess 92 which is adapted to receive a shaft 93, the extension 85 and the roll 3| being driven by the shaft 93.

The lower roll 3|, Figs. 8 to 10, has circumferentially enlarged portions or high spots 94 which act as platen pressers. These parts 94 are angularly disposed in such a manner that upon rotation they are brought into alignment with the angular position of the tape being fed and the angularly extending waxed portion on the paper 4. The heating unit 89, contained within the roll 3 I is for the purpose of heating the waxed portion of the paper 4, which may have cooled off to some degree, and assists the Wax in adhering the tape 35 to the paper`4.

The presser roller 32 is smaller in diameter than the roller 3|, but operates i'n conjunction therewith, being positioned immediately above the roller 3|.4 This roll 32 is fixed to a revolubly mounted shaft 95, Figs. 1, 11 and 12, and is of an increased width relative to roll 3|. Th-e shaft 95 is journaled at 96 to a bracket 91, which is fastened to a boss or projection 98 on a boss or lug 99, Fig. l2. The member 99 surrounds a shaft |88,'and is fixed thereto. The shaft |00 is freely or pivotally mounted in the angle bracket |8I. The angle bracket |8| is rigidly attached to theframe I by means of a bolt |02. Securely attached to the bracket 91 is an angular scraper arm |83 which engages the upper roll 32 to remove any excessive wax therefrom. The gearing 99 is free to have oscillatory movement with the shaft |08. To the rear of the roll 32, and mounted on the shaft 95 is a cam |84 which rotates with the shaft 95. This cam |84 has enlarged circumferential portions, Figs. ll-and 12, which contact a cam plate |85. The cam plate |85 is rigidly secured to the extension of the arm |86 which is rigidly fastened to a rigid stud shaft |01 by means of a bolt|88, Fig. 11. The plate |85 on the extension |86 extends into a position to be contacted by the cam |04.

When the cam |04, Fig. 12, engages the plate |85 it will cause the shaft |08 to turn in its bearing in the bracket |0| and move the roller 32 from its normal operating position, as shown in dotted lines in Fig. l5, to the full line position shown in that gure, and the web 4 will be in the position shown in Fig. Y15, providing sufficient clearanceto permit a piece of cut tape 35 to be properly positioned. Therefore, as soon as the cam` is off the member |85 the web 4 will be forced against the tape 35 and cause the tape to be adhered to the web.

A gear |89, Fig. l0, mounted upon the rotatable shaft 93 to rotate the roll 3|, co-operates with a gear ||8, Fig. 11, which is mounted on the end of the shaft 95 to rotate the cam |04 and the roll 32. Upon each rotation ofthe shaft 95'the high spots of the cam |04 are so positioned with respect to the high spot of the lower roll 3| to raise the upper roll 32 slightly away from the roll 3|. This clearance between the rolls 3| and 32 is of an amount substantially equal to the thickness of the tape and the waxed portion on the paper 4, and has the purpose of preventing too much pressure being applied by the pressure rolls 3| and 32, as too much pressure would cause the wax to be squeezed out from under the tape 35 onto the remainder of the paper. The arrangement provides the precise and predetermined application of pressure to properly adhere the tape 35 to the paper4.

The swivel mounting of the roll 32 on the bracket 99 is to allow for a free oscillation to provide the necessary spacing between the rolls. Also, the free oscillation of the roll 32 is such that it can be lifted up away from the roll 3| for cleaning purposes.

Beyond the superposing rolls 3| and 32 is a cooler or chiller unit ||9 which lies immediately above the laminated sheets. This chiller unit H9, Figs. 1, 13 and 14, may consist of a pipe |20 and elbow |2|, attached to and extending through the frame. The pipe |20 has air vents |22 so disposed to immediately lie over the portion of the sheet Where the tape was superposed thereto. 'I'hese vents |22 blow a stream of cold air (from a unit not shown) upon the tape, the paper and the roll 32 to cause the wax to become chilled and consequently expedite adhesion between the strip of tape and the sheet.

The laminated sheet is picked up by feed rolls |25 and |26, Fig. 1, which are mounted on transverse shafts |21 and |28, respectively, supported in the frame in any conventional manner. The roll |25 is mounted between pivoted arms to permit free vertical movement of this roll, while the lower roll |26 may be journaled in fixed bearings in the frame. A spring (not shown) is provided to urge the upper roll |25 into contacting engagement with the lower roll 26. A scraper arm |29 is fastened tothe frame in any conventional vmanner to remove any excessive wax which may become lodged on the roller 26, Fig. 1. The tape 35 is fed downwards from the rolls |25 and |26 to the feed rolls |30 and |3| which are mounted on shafts |32 and |33, respectively, and then downwardly into a pair of rotary transverse cutters |34 and |35fwhich are mounted on the rotatable shafts |36Iand |31, Fig. 1. The cutters |34 and |35 arefsynchronized with the feed of the sheet to cut the laminated sheet transversely along a line |38, as clearly shown in Fig. 7. This line of cut |38 is immediately adjacent the free end of the extending strip of tape which previously has been adhered to the sheet of paper. The shaft |33 may be a power shaft to drive the cutter roll |34 and its co-operating cutter roll |35. i

The shaft |33, Fig. 4, may have a sprocket |39 attached thereto over which a sprocket chain |40 passes, the chain |40 being driven by any prime mover such as a motor (not shown). On the shaft |33, behind the sprocket |39, is a gear (not shown) which engages an idler gear |4|, Fig. 4, mounted on a shaft |42, which drives a gear |43 mounted on shaft |28 for .the` feed roll |26,

Fig. 2. An idler gear |44 mounted on shaft |45` contacts the gear |43 and also contacts a gear (not shown) mounted behind the sprocket |46 on the shaft 93. The shaft 93 drives the presser roll 3| and the upper roll 32 through the gears |09 and ||0, see Fig. 11. The sprocket |46 is connected to a sprocket chain |41 which is connected to a sprocket |41a, Fig. 4, for driving the wax shaft 6 to rotate the wax roll 5. 'I'he gear `(not shown) behind the sprocket |46. also engages an idler gear |48 which in turn drives the gear 6| mounted on the shaft 69 to drive the shaft 54 through the coupling 59 and the shaft 60. Fig. 2, for the tape cutter rolls 5| and 52. The shaft 54, Fig. 3, has a gear |50 to contact-an idler gear I 5| mounted on shaft |52, which also engages a gear |53 mounted on shaft 41 for driving the feed rolls 44 and 45, Fig. 1. The ratio of the driving gears for feeding and cutting the tape, and for waxing and feeding the paper, and for the subsequent cutting of the laminated sheet is such that they are in synchronized relationship'with each other for the purpose desired.

In operation, the tape 35 is fed from the supply roll 34 through the guide channels 39 and 42 to the feed rolls 44 and 45, where it is fed into the cutting rolls 5| and 52. The cutting rolls rotate to cut the tape into a predetermined strip or length. The strip of tape is then fed through the guide channel 64 into the feed rolls 12 and 13, which feed the tape valong a horizontal guide member 82 where a pusher arm, co-operating with the feed roll shaft 16, positions the tape 35 accurately against the guide 82. In this position vthe tape is ready to be fed into the pressing rolls into contact withv the sheet 4.

The feeding of the tape up to this position has been at an angle with respect to the feed of the sheet 4. The sheet 4 is` fed around a guide roll 3 into contact with a waxing roll 5 which deposits a portion of wax thereon. The sheet 4, with its waxed portion, is fed around the tension rolls into contact with the pressure rolls 3| and 32, Where it is to receive the pre-cut strip of tape. The rolls 3| and 32 engage the strip of tape and the pre-waxed web of paper to press the tape into engagement with the wax on the web. The tape 35 is accurately fed from an angular position to correspond to the angularly disposed waxed portion on thev web 4. The presser rolls also feed the laminated sheet past a chilling unit I9 into the feed rolls |25 and |26, downwardly to contact the feed rolls |30 and 3|, where they are fed into the cutter rolls |34 and |35. The cutter rolls are rotated to cut the advancing sheet transversely on a line of cut |38 which is adjacent and in alignment with the free end of the extending strip of tape on the sheet.
